The prototype is beautiful, and seems to be based on leaked part specifications.

The video doesn't say that this is just Feld & Volk's version of the iPhone 6; the video is titled "iPhone 6 hands-on." And the coolest part is that it actually seems to work. Kind of.

But as 9to5Mac points out, there's one huge indicator that this is just a prototype and not a leaked actual iPhone 6: It's running iOS 7 and not iOS 8, the operating system the actual iPhone 6 will ship with.

You can tell because the iTunes logo that appears when the cord is plugged in is blue, not orange.

Here's what the new iTunes logo will look like in iOS 8 and on Yosemite, the new Mac operating system:

Still, the fact this prototype is working at all is pretty nifty, regardless of whether it's using iOS 7.
